RESILIENCE AND VULNERABILITY
----------------------------
RESILIENCE IS THE CAPACITY OF THE POPULATION TO COPE WITH A HAZARD. SINCE MUCH OF INVESTMENTS IN EARTHQUAKE PREPAREDNESS AND AVAILABLE FUNDS FOR QUICK RESPONSE IS RELATED TO HOUSEHOLD INCOME, THE GDP PER CAPITA CAN BE USED AS A ROUGH INDICATOR OF RESILIENCE.
UNITED STATES HAS A GDP PER CAPITA OF 30845 PPP$ (PARITY PURCHASING POWER DOLLAR, ABOUT 1 EURO) AND IS THEREFORE PART OF THE HIGH LEVEL INCOME COUNTRIES. THEREFORE, THE EARTHQUAKE HAPPENED IN AN AREA OF HIGH RESILIENCE.
BASED ON THE COMBINATION OF 9 INDICATORS, ECHO ATTRIBUTES UNITED STATES A LOW VULNERABILITY.
============================================================================================================

SECONDARY EFFECTS
-----------------
PROBABILITY OF SECONDARY EFFECTS:
- LANDSLIDES: THE MAXIMUM SLOPE IN THE AREA OF THE EARTHQUAKE IS N/A% AND THE MAXIMUM ALTITUDE IS N/A M. SINCE THIS IS A LOW SLOPE, THE RISK OF EARTHQUAKE INDUCED LANDSLIDES IS LOW. NOTE, HOWEVER, THAT THE SLOPE DATA IS NOT RELIABLE ON A LOCAL SCALE, WHILE LANDSLIDES DEPEND VERY MUCH ON LOCAL TOPOGRAPHY, SOIL AND METEOROLOGICAL CONDITIONS.
- NUCLEAR POWER PLANTS: THERE ARE NO NUCLEAR FACILITIES NEARBY THE EPICENTER.
- HYDRODAMS: THERE ARE NO HYDRODAM FACILITIES NEARBY THE EPICENTER.
